Abstract: Embodiments of the present application provide a dental robot and an oral navigation method. The dental robot comprises a tandem positioning arm, wherein the tandem positioning arm comprises a pedestal, several positioning arms and a jacket, and the jacket is configured to clamp surgical instruments; the pedestal, the several positioning arms and the jacket are connected in series in sequence by rotary joints; a joint angle measuring device is mounted at each of the rotary joints. According to the dental robot and the oral navigation method provided by the present application, by the lightweight of the tandem positioning arm, the volume and weight of the dental robot system are reduced, which improves the practicality of the dental robot in surgical operations.

Abstract: A method for calculating areas of farmable land for the working of agricultural machinery, applied in an electronic device, obtains data as to specific locations and data as to time-points of agricultural machinery within a time period when working normally, and processes and cleans the data time-point data to remove data of location and time-points which are time-point data not in a normal operation state because of repeated traverses and time spent in non-operating states. The electronic device clusters and segments the location and time-points data and time-point data distinguishes between time-point data of the agricultural machinery in a normal operation state and data in non-operating or repeating states. The location and time-points time-point data of the agricultural machinery in the normal operation state are retained. The electronic device generates polygons based on the retained time-point data and calculates operable areas according to the polygons.

Abstract: A Multiform Suspension Microgranular Bioreactor (MSMB) is used to detect nucleic acids or peptides/proteins in molecular and biological samples. Polymer-based microgranules, coupled with biomass molecule probes, are constructed with different features. The biomass molecule probes include cDNA probes, oligonucleic acid probes, peptide or protein probes. These microgranules are differentiated according to their features including shape, size, color, fluorescence intensity, magnetic property, gravity, chemical luminal intensity, radioactivity, and other labels. The above microgranules are suspended in a sample solution and are used collectively as a microarray-like bioreactor device. Such MSMB-based microarrays are particularly useful in complicated biological detection assays with flow cytometry.
